1. Group carbohydrates (polypeptide-polysaccharide complexes) were separated from Group A and Group O pig stomach mucus, and their properties were compared with each other.
2. They differed not only in group specificity but also in optical rotation and possibly L-fucose content, but not in the other physical and chemical properties examined (composition, HIO4- and NaIO4-use and else).
3. It looked that the components or partial structures causing the optical rotatory discrepancy between the group carbohydrates are inert to HIO4 and acid.
Through the Grant Committee for Scientific Researches was given a grant from the Education Department in aid to us. H. Masamune.
